Description
A high-performance low-level radio frequency (LLRF) control system based on ZYNQ MPsoc has been developed to enable the digital and intelligent upgrade of Shanghai Soft X-ray Free-Electron Laser (SXFEL). It includes 8 channels of 310 MSPS 16-bit ADCs and 2 channels of 500 MSPS 16-bit DACs, capable of outputting continuous wave and pulse wave signals, respectively. The LLRF control system is equipped with an FMC(LPC) interface to communicate with the White Rabbit(WR) device in the control system, providing feedback on the SXFEL' s orbit, focusing, and beam energy states. In experimental measurements on SXFEL, the LLRF system achieves a amplitude stability of 0.016% (RMS) and a phase stability of 0.015o at pulse compressor output.
